Fire Resistance SBI BS EN 13823 Single Burning Item Test For Building Materials

Fire Resistance SBI BS EN 13823 Single Burning Items For Building Materials

BS EN 13823 SBI Product Introduction:

The sample is placed on a mobile cart located in the exhaust system so that the combustion reaction of the sample can be displayed and visible automatically. Calculating the heat release rate (HRR), smoke release rate (SRR), and other physical properties evaluated by visual observation to evaluate the combustion characteristics of the machinery. The fire growth rate index (FIGRA) is the most representative measure factor in the SBI measurement range; there are also factors measuring oxygen consumption representative, CO, CO2 generation amount, smoke growth rate index (SMOGRA), and so on. The maximum heat release rate is 1MW.

BS EN 13823 SBI Standards:

• BS EN 13823
- Reaction to fire tests for building products-Building products excluding floorings exposed to the thermal attack by a single burning item

BS EN 13823 SBI Technical Specification:

BS EN 13823 SBI Features:

1.A trolley, a fixed frame, a gas collecting hood, a collector, a J type exhaust pipe, a centrifugal fan, a wind speed control device, the comprehensive measurement section, a gas analysis cabinet, and a data acquisition system comprise the Single Burning Item (SBI) test system.

2.Two vertical sample specimens can be installed on the trolley. A sand box burner is located at the bottom of the vertical angle. Surface ignition is used, and the flame detection system includes a flameout protection device.

3.The gas collecting hood is supported by the fixed frame. As a flameout protection device, the frame is fitted with an auxiliary burner and a flame detecting system.

4.Stainless steel gas collector at the top of the fixed frame for collecting combustion gases;
a stainless steel J-type smoke exhaust pipe with a 50mm high temperature resistant mineral cotton insulation and an inner diameter of 315 + 5 mm;

5.The smoke exhaust system must convert frequencies to continuously expel smoke at a rate of 0.50 m3/s to 0.65 m3/s;
a mass flow controller with a 0g/s to 2.5g/s measurement range and a reading accuracy of at least 1.5%;

6.The flow rate of the gas supply may be automatically adjusted between 647 mg/s and 2000 mg/s, and the gas control system can ensure that the speed of the gas supply during test changes should not be greater than 5 mg/s, ensuring the production of heat of 30.7 + 2 kW;

Ignition System:

• 10kV spark ignition, a cease-fire with safety devices. Ignition automatically positioned by a lever mechanism connected to a closed
• import mass flowmeter input flow control.
• flame extinction has automatic alarm device, safe and reliable.
